By the end of today's class, you should be able to do the following:

Review:  Just how thick is the crust?  mantle?  core?

Describe the differences between the two kinds of crust in terms of thickness, density and overall color of the major kind of rock that occurs there, and where on Earth the two types of crust occur. 

w Draw a to-scale diagram illustrating the internal structure of the Earth, including crust, mantle, and core.

w Review: How did the Analysts and Peer Reviewers do at identifying geotectonic patterns?  ("Teams will earn one point for each valid and supportable pattern they come up with, and Peer Reviewers will earn a half-point for each one they review correctly and pass to the instructor.  Total possible points:  7.5.")

w Explain the difference between brittle deformation and ductile deformation.

w Describe the characteristics of the lithosphere and asthenosphere.

w Sketch a diagram of the internal structure of Earth illustrating the positions of the lithosphere and asthenosphere.

w Describe the basic principles of geotectonic theory.

Examining a map of geotectonic boundaries, add the information about boundary type to your collection of information about our fourteen study sites.
